Tomahawk columns tag

This tag is used to allow dynamic number of
columns for a dataTable. This creates columns iterating through
datamodel. Its "value" attribute takes all the values which
its wrapper datatable's "value" attribute can take. In other
words "value" attribute can accept DataModel, List, Array.
"Var" attribute is used to access the current column in the
iteration. Using this columns tag we don't need to write many
column tags. This iterates over the datamodel and produces columns for
the datatable. It provides many attributes for
header and footer of the column which can be used to provide new
functionality in the columns. Its sorting capability is really very
good. We can sort the columns by clicking the column header if the
sorting attribute is set to true. Default sorting can also be applied to
get the column sorted automatically when the page is rendered and
sorting according to the property can also be applied.
